But after he reviewed the clip he discovered something mysterious in the sky.

“If we brought some contrast into the footage we can witness what can only be described as a cube,” he says.

“We can now see what the viewer saw. He noticed a faint line in the clouds that gave him an impression it was geometric.

“Had this been just a clear blue sky, I doubt we will be seeing anything at all. So then you have to ask yourself are we seeing some sort of cloaking mechanism because clouds do not move and form in this way.

“The cube, or square-shaped, is one of the most mysterious as it’s the one we rarely see and the most elusive you will see.”

Viewers had mixed reactions to what the object could be, with one suggesting it “is a cloaked vehicle that was un-cloaked by indirect light”.

Another added: “That has to be some sort of alien spaceship.”

But a third disagreed, writing: “Clearly just a glitch in the camera.”
